Question

I have a PHP Loop that loops through data, i want to be able to echo all of this data alphabetically.
i currently use an array:
$output[]=array();
foreach($WHM_Servers as $whm) {
foreach($server->list_accounts() as $ret) {
$output[]= '<tr class="notfirst">
<td>'.$ret["domain"].'</td>
<td>'.$ret["user"].'</td>
<td>'.CompanyInfoLookup($result["customer"], 'company').'</td>
<td>'.$ret["startdate"].'</td>
<td>'.$ret["starttime"].'</td>
<td>'.$ret["disklimit"].'</td>
<td>'.$ret["diskused"].'</td>
</tr>';
}
}
would i be able to add a key in the array and then echo the array alphabetically from the keys

Answer 1

A few different ways to do this, I chose to write a user defined sort function.
$accounts = array();
$accounts[]['name'] = "Tom";
$accounts[]['name'] = "Frank";
$accounts[]['name'] = "Zed";
$accounts[]['name'] = "Aaron";
function compareNames($a, $b){
return strcmp($a['name'], $b['name']);
}
usort($accounts, "compareNames");
var_dump($accounts);
Output:
array(4) {
[0]=>
array(1) {
["name"]=>
string(5) "Aaron"
}
[1]=>
array(1) {
["name"]=>
string(5) "Frank"
}
[2]=>
array(1) {
["name"]=>
string(3) "Tom"
}
[3]=>
array(1) {
["name"]=>
string(3) "Zed"
}
}
This is a standalone example. To apply it to your example, you need to store the data: $accounts = $server->list_accounts(), sort it: usort($accounts, "compareNames");, and then pass it in to your loop: foreach($accounts as $ret) {
